Mandibular Fractures: I. An Analysis of Their Etiology and Location in 286 Patients

Abstract
Case histories were studied of 286 patients treated for mandibular fractures; 46.5% of the patients were aged 18-30 yr and 73.4% were male. Mandibular fractures associated with mid-face fractures were most frequently caused by traffic accidents (81%). When the mandible alone was fractured traffic accidents accounted for 50%, while assaults were responsible for 20%. Accidents at work only occurred among the men. Of the 487 mandibular fractures the most frequent site was the condylar process (36%) where half of the fractures in women were localized. Assaults most frequently caused fracture of the angle of the mandible; while falls were most frequently responsible for fracture of the condylar process. The fracture distribution in dentulous and edentulous mandibles differed despite the etiology being the same.
